Sun & skin: a deeper connection than just a tan

When we think of the sun and skin, the first image that often comes to mind is that of a beautiful tan or, unfortunately, a sunburn. However, the relationship between skin and the sun is much more complex. The sun plays a major role in our health, with both positive and negative effects on the skin.

In this article, we will explain the moderate benefits of the sun, the less visible risks associated with sun exposure, and why it is essential to use appropriate care to protect and strengthen the skin.

The benefits of the sun on the skin and health

Vitamin D: an essential health asset

Sun exposure allows the skin to synthesize vitamin D, which is essential for bone health, the immune system, and the prevention of certain diseases. Moderate sun exposure is therefore recommended to maintain good natural vitamin D levels.

Sunshine to improve mood

Sunlight stimulates the production of serotonin, a hormone that improves mood and reduces stress. This explains why sunlight is often associated with increased mental well-being.

Regulation of biological rhythms

Sunlight helps synchronize the circadian rhythm , the internal clock that regulates sleep-wake cycles. Daily exposure to natural light improves sleep quality and vitality.

The less visible negative effects of the sun on the skin

Skin dehydration due to the sun

UV rays cause water loss from the skin's surface, leading to dehydration . Dehydrated skin is more sensitive, less supple, and more susceptible to external aggressors.

Oxidative stress: a key factor in aging

UV rays promote the formation of free radicals, which are responsible for oxidative stress . This phenomenon damages skin cells, accelerating premature skin aging, with the appearance of wrinkles and pigment spots.

Premature aging and cellular damage

Chronic sun exposure without adequate protection causes alterations to the DNA of skin cells. This premature cellular aging increases the risk of skin cancer and permanently damages the epidermis.

Why use a sunscreen specifically formulated for the skin?

Sun protection is essential to limit these negative effects. But simply filtering UV rays isn't always enough. It's also necessary to support the skin, strengthen its natural defense mechanisms, such as DNA repair, combating oxidative stress, and hydration.

An innovative approach to photoprotection therefore consists of supporting the skin in its natural processes, rather than simply creating a barrier. This supportive care is essential for preserving the skin's health and youthfulness.

Towards a new generation of skincare: strengthening the skin

This new vision of sun protection is embodied by products like SUN DEFENSE . This unique treatment contains no UV filters or SPF, but works by strengthening the skin's natural resistance to the sun.

In our next article, discover how SUN DEFENSE MONO supports the skin against sun damage, reducing redness and increasing UV tolerance, while respecting the environment.

The sun is essential to our health, but it also poses numerous challenges for the skin. A thorough understanding of this relationship encourages us to adopt intelligent sun protection that combines effectiveness, durability, and respect for the skin.
